[Rahul Shivsharan]

I have set hibernate.cfg.xml in class path ie. this file is in the root folder "src" .

The persistence.xml is in src/META-INF folder which is also in the class path .

the jars which i have added are as follows
ejb3-persistence.jar,
ojdbc14.jar,
ant-antlr.jar,
asm.jar,
asm-attrs.jar,
cglib.jar,
commons-collections.jar,
commons-logging.jar,
dom4j.jar,
ehcache.jar,
hibernate-anottation.jar,
jta.jar,
hibernate-entitymanager.jar,
hibernate3.jar
log4j.jar,

this is my persistence.xml

 <?xml version="1.0" encoding="UTF-8"?>
